Abstract: A communication method and a system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with an internet of things (IoT) technology are provided, which may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and an apparatus for transmitting a reference signal are provided. The method includes receiving, from a base station, a first parameter and a second parameter associated with a sound reference signal (SRS) by higher layer signaling, identifying a bandwidth for the SRS based on the first parameter and the second parameter, and transmitting, to the base station, the SRS based on the identified bandwidth for the SRS.

Abstract: The disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The t disclosure may be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. A method in a wireless communication system is provided. The method includes transmitting channel state information reference signal (CSI-RS) configuration information to a terminal, the CSI-RS configuration information used for a CSI-RS resource set which includes a plurality of CSI-RS resources and information on CSI-RS repetition, transmitting a plurality of CSI-RSs based on the CSI-RS configuration information to the terminal, and receiving feedback information from the terminal, wherein the information on CSI-RS repetition indicates whether the plurality of CSI-RSs are transmitted based on a same transmission beam repetitively.

Abstract: Various communication techniques and related systems for a fusion between a 5th generation (5G) communication system and Internet of Things (IoT) technology are provided. A user equipment (UE) is required to select a dedicated core network so as to receive a suitable service. In a method for transmitting and receiving a signal, an enhanced Node B (eNB) of a mobile communication system transmits a first request message to a first mobile management entity (MME), receives a reroute command message based on the first request message from the first MME, and transmits a second message to a second MME based on the reroute command message. Herein, the reroute command message contains the first request message, at least one MME identifier, and a UE identifier.
